BOBBIN HOLDER or YARNYW'INDIYNG srmnms I Application filed September 23,1927f Serial No. 221,476.

Thifi lg invention relates to bobbin holders designed for use withspindles of yarn winding machines; and the object 1S to provide for theready removal of the accumulated yarn on the bobbin holder without the.use of a yarn cutting instrument as is necessary with the present typesof holders.

With this object in view, the invention consists of certain novelfeatures of construction, as will be more fully described andparticularly pointed out in the appended claims.

In the accompanying drawings Figure 1 is an elevation of a port on of awell known type of yarn windin'gmachine showing a spindle and itsbolster casing, my improved bobbin holder, and a bobbin with its yarnload, the latter in dotted lines. Figure 2 is an axial section of thebobbin holder in detachable connection with the friction collar. Figure3 is a lan view of the same, Figure 4 is an elevationof the frictioncollar; and Figure 5 is an elevation of the bobbin holder.

Referring to the drawings, in which like numerals indicate correspondingparts wherever occurring, 10 represents a portion of the stationary railof a yarn winding machine for supporting the bolster 11 in' which thespindle 12 is rotatable. Above the rail and rigid with the spindle isthe whirl 13,

adapted to be positively driven by a' band from a drum (not shown) inthe usual man; ner. A collar 14 rotatable on the spindle is infrictional contact with the top of the whirl through a yielding pad 15interposed between the collar and whirl. The collar is provided with ahub 16 to which the bobbin holder 17 is detachably securedand rotatabletherewith. The'bobbin 18, loosely mounted on the spindle, is detachablyconnected by suitable means to the top of the bobbin holder, therotative movement of which depends upon the degree of friction existingbetween the whirl, the yielding pad and the friction collar. I Thebobbin holder 17 consists of a circularbody the upper end of which isenlarged forming a flange having a central tubular stud 19, which isadapted to fit into the base of the bobbin, and through which thespindle loosely passes. The holder and bobbin are detachably connectedtogether by any suitable means, preferably by apin 20 fixed to theflange and adapted to coact with a socket in the base of the bobbin..The lowerportion of the holder is counterbored to slid ably fit on thehub 16 of the friction collar and is detachably secured thereto bysuitable means, preferably by a bayonetjoint comprising a pin 21 fixedlypositioned to the periphery of the'hub 16 and coactir'g with a groove 22cutin the surface of the counterbore 23 ofthe holder. The periphery ofthe lower ortion of the holder is tapered downwar from the. underside ofits flanged'top thus facilitating the removal of yarn accumulatedthereon from dofi'ed bobbins. i

In operation the spindle 12 is rotated independently of the bobbin byits whirl, and the friction collar 14 and the bobbin holder 17 thereonare rotated by friction between the yielding pad 15 and whirl upon whichthe friction collar rests, thereby maintaining the proper tension uponthe yarn while being wound on the bobbin. After the bobbin has beenfilled and is ready for dofiin the traverse motion rod24 with yarn ui e25 mounted thereon. is at the top 0 the bobbin, and the operator thenlowers the guide below the bobbin so that the yarn-26 is wound on thetapering surface'of the hub of the bobbin holder, and the filled bobbinis removed and replaced by an empty one, so that 'a continuous strand ofyarn is retained ready for repeating the operation upon the unfilledbobbin. The guide rod is then raised to guide the yarn to the lowestpulls the bunch of yarnfrom its position n the tapering body of theholder. By this construction less time is taken b the operator inremoving the accumulate yarn than is now required in the use of acutting instrument.

I claim 1 1. In a spindle, a blade, a whirl, a collar frictionallydriven by said whirl, a bobbin holder supported on said collar and,havin a bobbin engaging top portion and a conica yarn receiving bodyportion tapering continuousl downward to said collar, and means ordetachably securing the collar and holder, said means being eifective tolock said holder to said collar and to prevent axial separation of saidparts.

2. In a spindle, a blade, a whirl,'a collar frictionally driven by saidwhirl and havingan upwardly projecting hub, a bobbin holder slidable onsaid blade and resting on said collar and recessed to receive the hub ofsaid collar, said holder having a bobbin engaging top portion and aconical yarn receiving body portion tapering continuousliy downward tosaid collar, and means for gtachably securing the hub of said collar andthe recessedv portion of said holder together, said means beingeffective to lock said holder to said collar and to prevent axialseparation of said parts.

In testimony whereof, have signed this specification.
